ALARMING DEVICE Application filed February 2, 1928.

This invention relates to alarm clocks, and more particularly to alarming devices in which an electrical circuit is closed at a. predetermined time.

In the usual alarm clock a bell rings at the prescribed time to awaken the sleeper; but after this has been accomplished the clock has served its purpose. However, it is possible to so connect the alarming operalu tions with an electrical circuit so that certain electrical appliances may be placed in operation and thus save time for the sleeper and make his initial duties upon awakening more convenient and easier.

It is an object of this invention to provide an alarm clock in which an unwinding main spring serves to close an electrical switch, at a prescribed time, to cause an electric lamp to light, and to place in operation such accessories and appliances as an electric heater, a wafile iron, coffee percolator, etc, generally used by persons upon arising.

This and other objects are attained by the novel construction, combination and arrangement of parts hereinafter described and shown in the accompanying drawing, constituting a material part of this disclosure and in which:

Fig. 1 is a front elevational view of an alarm clock equipped with a contact device, made in accordance with the invention.

Fig. 2 is a side View of the clock.

Fig. 3 is a schematic View of the switch and circuit employed.

Referring to the drawings, an alarm clock 4 is shown to have an alarm spring 5 which is normally maintained in engagement with the plunger 6 by means of the spring 8 bearing against the flange 7 integral with the plunger; the other end of the spring 8 resting on the plate 9, which is provided with an aperture through which the plunger passes.

Mounted on the lower end of the plunger 6 is an insulating strip 10, which is so positioned that its longitudinal axis is oblique to the longitudinal axis of the plunger. The insulating strip 10 carries at one end a contact 11, and at the other end the contact 14.

Positioned below the strip 10 is a second Serial No. 251,251.

insulating strip 18 provided with contacts 11 and 15 at its extremities, these contacts being connected by a copper strip or wire 18 embedded in the insulating strip 18, and the copper strip or wire is connected to the negative terminal of the source of power.

The contact 11 is in circuit with an electric lamp 12, preferably red in color, and also in this circuit is provided a switch 13, which is connected to the positive terminal of the source of power.

The contact 14 is in circuit with a percolator, electric heater, or similar appliance, which is connected to the system by the leads 16. i i

In operation, when a person desires the improved alarm clock to function, the switch 13 is closed, and the alarm set for a specified hour. As the spring 5 unwinds it forces the plunger 6 downward, and when the specified hour has been reached the plunger will be forced down a distance suflicient to make contact between contact elements 11 and 11, with the result that the electric lamp 12 will light, the circuit now being closed. As the spring 5 continues to unwind, it forces the plunger and insulating strip 10 downward until contact is made between elements 14, 15, which closes the circuit governing the operation of the electrical appliance connected by the leads 16. It will be observed by reference to the drawings that the lighting circuit is independent of the electrical appliance circuit.

From the above description it will be seen that I have provided an alarm clock having means for indicating visibly the time of the day, and subsequently, to start the operation of an electrical appliance, thereby saving considerable time and labor on the part of the user. A clock as herein described enables a person to sleep later and yet accomplish all the functions possible with the ordinary alarm clock.

The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention, of which obviously an embodiment may be constructed including many modifications without departing from the general scope herein indicated and denoted in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In combination with an alarm clock, a plunger moved downwardly by the unwinding of an alarm spring, an insulating strip, provided with a pair of contact members, mounted on the lower end of the plunger, one of said contact members being adapted to complete an electric circuit when the alarm spring unwinds a predetermined distance, and the other contactmember being adapted to subsequently complete another electric circuit as the alarm spring continues to unwind.

2, In combination with an alarnrclock, a

olun' er moved downwardly by the unwinding of an alarm spring, means to normally engage said tplunger with the alarm spring. an insulating strip, provided with a pair of end contact members, 'IIIOUHtBCl'OD the lower end of said plunger, a secondinsulating strip, provided with a contact member. said insulating strips being so positioned relative to'each other, that when the :alarm spring unwinds a predetermined distance, one contact memher on the first mentioned insulating strip contacts with the contact member on'thesec- 0nd insulating strip to completean electric circuit, and as the alarm spring'continues to unwind the other contact member on the first mentioned insulating strip contacts with the contact member on the second insulating strip to complete another electric circuit.

3. In combination with an alarmclock. a plunger moved downwardly by the unwinding of an alarm spring, a springenyeloping said plunger adapted to normally engage said plunger with the alarm spring, an insulating strip mounted on the lower'endof said plunger. contact members mounted on the extremities of said insulating strip, a second insulating strip positioned below said first mentioned insulating strip, one of said insulating strips'being in oblique relation to the other, contact members mounted-on the extremities of said second insulating strip and opposite the former contact members, and a conductor imbedded in said second insulating strip electrically connecting said latter contact members, vone set of opposed contact members being adapted'to complete an electric circuit when the alarm spring unwinds a predetermineddistance, andthe otherset of opposed contact members being adapted to subsequently complete another electric circuit as the alarm spring continues to unwind.

In testimony whereof I have allixed my signature.

STEPHEN GORAZZO.
